Yellow Archangel is a noxious weed

The State of Vermont is considering whether to add yellow archangel (Lamium galeobdolon) to its list of Designated Noxious Weeds. As a noxious weed, the distribution and sale of yellow archangel would be regulated, which is probably a good thing since the plant has the potential to become a serious problem in Vermont. It is already listed as a noxious weed in Washington and Oregon.

Lamium galeobdolon sensu lato is native across Europe, western Asia, and portions of the Middle East. Lamium galeobdolon subsp. argentatum, known as the variegated yellow archangel, has been well documented as an invasive subspecies in several European countries where it outcompetes the native subspecies galeobdolon. Yellow archangel has been introduced into North America but the subspecies is unknown. In Washington, Oregon, and British Columbia, the invasive entity is listed as Lamiastrum galeobdolon. If Vermont chooses to list this taxon, the following name is recommended:

• Common name: yellow archangel
• Scientific name: Lamium galeobdolon
• Synonym: Lamiastrum galeobdolon

The name Lamium galeobdolon is here used as the name of a (sub)species complex that includes all yellow-flowered taxa in genus Lamium (including Lamium galeobdolon subsp. flavidum, which is thought not to be invasive).
